More Information
Summary:The invention relates to a motor heat dissipation structure, which comprises a casing, stators arranged in the casing, a rotor sleeved between the stators, a liquid cooling channel wound in the casing and an air cooling channel for cooling the casing, the stators and the rotor, and is characterized in that the liquid cooling channel is filled with cooling liquid and is used for exchanging heat with the casing; the cooling of the shell is realized; the air cooling channel comprises a plurality of cooling air inlets, a rotor air cooling channel communicated with the cooling air inlets, a stator air cooling channel communicated with the rotor air cooling channel, a machine shell air cooling channel communicated with the stator air cooling channel and a cooling air outlet communicated with the machine shell air cooling channel. According to the motor heat dissipation structure, radial cooling, axial cooling and rotary sealing are combined, and countercurrent flow heat exchange is achieved in the axial direction.
